EDWIN REYNOLDS, OF MILVVAUEEE, WISCONSIN.

COMBINED STEAM GENERATOR AND RADIATOR.

SPECIEIGATION forming part of Letters Patent No. 345,991, dated July 20,1886.

i Application tiled November 4, 1885. Serial No. 181,843. (No modeLl Toa/ZZ whom it may concern:

Beit known that I, EDWIN REYNOLDS, of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented certain new and usefulImprovements in Combined Steam- Generator and Radiator, of which thefollowing is a specification.

Myinvention has reference to the heating of buildings; and it consistsin a combined steam-generator and radiator hereinafter more fullydescribed, in which the heat of the fire is first imparted to the waterin the generator, and by the water to air passing through tubes or iluestraversing the generator. By this plan the apparatus is caused to giveheat to the rooms from the moment the temperature of the water risesabove that of the incoming air, instead of requiring a temperature of212 and upward before the heating begins, and the benefits of the fuelare more completely utilized than heretofore.

The manner of carrying out my invention may be varied greatly as todetails, the only essential requisites being that the products ofcombustion be made to heat the water of the generator and that the waterbe in turn caused to heat a body of air passing through said generator.

The setting of the furnace, the particular arrangement of re and airfines, and other like matters may and will be varied to suit theparticularlocation, arrangement, and size of the building or apartment-sto be heated,

the character of the fuel to loev used and other influencingconsiderations.

In the drawingslhaveillustrated two slightly differing plans embodyingmy invention.

Figure l is a vertical sectional view of my generator and radiatorshowing the fire-pot directly beneath the generator, the lire or smoketlues passing vertically through said generator, and two sets ofair-iiues traversing the same horizontally at right angles to eachother. Fig. 2 is a horizontal section on the line x of Fig. l; Fig. 3, alongitudinal vertical section ofthe combined generator and radiator,showing the re or smoke tubes or flues arranged horizontally in twoseries, and the airilues traversing the generator both horizontally andvertically at right angles to the re tubes or tlues. Fig. 4 is ahalf-sectional front elevation of the apparatus shown in Fig. 3. Fig. 5is a vertical sectional View of the same on the line of Fig. 3, lookingtoward the rear, t-he flue-plate partially broken away; Fig'. 6, ahorizontal section on the line z z of Fig. 3.

The manner of utilizing or applying the heat produced by my improvedapparatus may be varied to suit special cases or requirements. Thus Ipropose in some cases to employ no outside radiators, but to rely solelyupon the heating of the requisite volume of air to proper temperaturewithin the apparatus itself, the heat of the water being so far reducedor kept down by the cooling effect of the air passing through the fluesthat no steam shall be formed, and warm air alone being produced andcarried to the rooms. In other cases, and especially where by reason ofinsufficient draft of the iiues or great exposure of the apartment to-be heatedthere maybe difficulty in delivering a due amount of warm airthereto, I contemplate employing radiators in such apartments andcarrying steam thereto from the generator.

In order that the apparatus may be susceptible of use in either way atwill, and without change in construction, l provide the same withair-inlets of ample capacity to furnish the full amount of air likely tobe required under any circumstances, and I furnish such inlets withvalves or gates by which their capacity may be reduced, and thetemperature ofthe water consequently allowed to be raised sufficientlyto produce steam. To further provide for the reduction of steam whenrequired,

the furnace is supplied with drafts and regulators.

-Referring now to the drawings, A indicates the external casing or bodyol" the apparatus; B, a fire box or chamber provided with a suitablegrate, C; and D, the generator, a steamtight body, advisably of wroughtiron, put together in the usual manner of constructing steam-generators.

E E indicate smoke or tire tubes opening sets, the first extending fromthe fire-box to a` IOO smoke-chamber, a, at the rear of the generator,and the second set returning from said smoke-chamber a to a similarchamber, b, at the front, from which the smoke and products ofcombustion pass off through a p ipe, F, to a chimney or directly to theatmosphere. The iiames andproducts of combustion thus passing throughthe flues or tubes E heat the water which surrounds them in thegenerator D, with.

the exception of the upper tier, ordinarily.

Passing through the body of the generator D, from side to side and fromfront to rear when the vertical re or smoke tubes are employed, as inFig. 1, or passing through said body from side to side and from top tobottom when the smoke or tire tubes are arranged horizontally, as inFig. 3, are air tubes or ilues G.

Diaphragms H, arranged within the outer easing, A, and generator-body D,serve to separate the cold-air space c from the warm-air space d, andair is admitted to thespace c through suitable inlets, I, as indicatedin the several figures. The smoke-spaces a and b are also inclosed andseparated from the air-spaces, as illustrated in the drawings. Airentering the inlets I, and prevented by the diaphragms H from enteringdirectly into the warm-air space d, is carried to the cold-air ends ofthe air-dues G, which it traverses, and through which it passes to thewarm-air space d, from which .it is conveyed by pipes to the requiredpoints, as in any ordinary warm-air heating system.

In passing through the tubes Aor lines G the air takes up a largepercentage of the heat of the water, and of course by `just so manydegrees reduces or keeps down the temperature of the water. In otherwords, the apparatus acts upon the principle of a condenser, and so longas the volume oi' the air and its temperature are sut'licient to take upall heat of the water from 212o upward no steam will be formed; butwhenever the cold air fails to thus take up all heat from 212 upwardsteam will be formed at a rate varying with the temperature of thewater.

The air-inlet I is furnished with a valve, J, by which the volume ofcold air entering the radiator may be varied and controlled, and Iofcourse as the volume is lessened the amount of heat taken up in passingthrough the dues G will be correspondingly lessened and the temperatureof the water increased. So, too, the furnace is provided with adraft-regulator, K, or the draft and the combustion may be controlled byopening or closing` the fuel and ash-pit doors, and in this way thetemperature of water may be varied, so that by properly regulating thelire and the air-supply, each in relation to the other,the action oftheapparatus can be accurately controlled, and steam may be formed or not,and a large or a small volume of air may be heated to a moderate or ahigher' temperature, as circumstances require.

The furnace will be provided advisably with a steam-draft regulator, L,and will of course have water and steam gages M and N and safety-valveO.

An automatic valve may be provided, if desired, to supply water to andmaintain it at proper level in the generator.

It is obvious that one or more large lire and air lines may besubstituted for the numerous small ones, but not with as good results.

I am aware that it is not new to provide a generator with air-dues, andthat it is also old to construct a heating-drum with air-fines at rightangles to one another, and to these features, perse, I lay no claim. Iam not aware, however,that anyone has heretofore provided a generatorwith two sets of ues or passages for the travel of the fresh air throughthe waterreceptaele, the fines of one set being arranged at rightangles, or substantially so, to those of f the other set. Under thisarrangement I am enabled to utilize to the greatest possible extent theheat of the water, insuring an economical use of 'fuel and anexceedingly compact construction and arrangement.

Having thus described my invention, what I claim isl. In combinationwith a casing, A, a fireboX, B, generator D, provided with smokeilues Eand with two sets of air-lines, G, those of oneset crossing those of theother, and diaphragms separating the smoke and air spaces.

2. The combination of casing A, re-box B, grate C, water-vessel D,ire-lues E, a smokechamber at the end of said iiues, smoke-pipe F,air-dues G, diaphragm H, and air-inlet I.

3. In a heating apparatus, a steam-generator provided with smoke-linesand with two sets of lues or passages for the travel of fresh airthrough the water-receptacle, the air-flues of one set being arranged atright angles, or substantially so, to those of the other set.

et. A vessel 'for heating purposes provided with suitable air and firetubes and with siX rectangular sides, all of said sides being supportedby and connected to the air and iire tubes to withstand internalpressure, asshown and described.
